Kammerhof
One the most important historical and administrative structural complexes in the region, Kammerhof is a constructional composite with some walls at least seven centuries old. Its Renaissance image, as you can see it today, was built in 1550 during a renovation when several older buildings merged into one. Kammerhof was a strategic building, where miners brought the ore that was then weighed, registered, and checked for quality in the laboratory. The ore of the highest quality was transported into mint in Kremnica.
During the Ottoman raids, Kammerhof was fortified to protect the wealth accumulated there. On the south-east side of the building, the fortification walls and bastions have been preserved and renovated.
Today, you can view the permanent exhibition "Mining in Slovakia," which presents the history of technologies used in Slovak mines. Functioning models of mining machines are part of the exhibition.
